struct S { // Provide a default constructor by adding an empty function body. S() {} }; union { struct { S s; }; } u; 具匿名結構的等位 為了符合標準,此執行階段行為為了等位中匿名結構的成員而有所變更。 建立這類等位時,不再隱含呼叫等位中匿名結構成員的建構函式。 此外,當此等位超出範圍...
struct S { // Provide a default constructor by adding an empty function body. S() {} }; union { struct { S s; }; } u; Unions with anonymous structs In order to conform with the standard, the runtime behavior has changed for members of anonymous structures in unions. The constructo...
struct S { // Provide a default constructor by adding an empty function body. S() {} }; union { struct { S s; }; } u; 具有匿名结构的联合 为了符合标准,已对联合中的匿名结构的成员更改了运行时行为。 创建此类联合时,将不再隐式调用联合中的匿名结构成员的构造函数。 此外,联合超出范围时,...
ActiveSubmaps2D::CreateGrid执行创建概率图,刚创建的概率图有个固定尺寸,100(kInitialSubmapSize)x100,换到真实世界是2.5mx2.5m。随着点云不断到来,新点云有些点落在了概率图之外,这时得扩大概率图,Grid2D::GrowLimits执行这个扩大。 point。基于点云会生成个Eigen::AlignedBox,它往往是这个AlignedBox的左上角、右...
Matrix3D Returns a new Matrix3D object that is an exact copy of the current Matrix3D object. clone() — method, class flash.geom.Point Creates a copy of this Point object. clone() — method, class flash.geom.Rectangle Returns a new Rectangle object with the same values for the x, y,...

After declaring variables for the input and output signals, the mdlOutputs functions uses an if-else statement to create blocks of code used to calculate the output signal based on whether the S-function uses a fixed-step or variable-step solver. The if statement queries the length of the ...
You can create a NULL pointer to pass to library functions in the following ways: Pass an empty array [] as the argument. Use the libpointer function: p = libpointer; % no arguments p = libpointer('string') % string argument p = libpointer('cstring') % pointer to a string argumen...
it's recommended to set a custom Makevars file with extra compiler optimizations, and then install the package from source. On Linux, simply create a text file~/.R/Makevarscontaining this line:CFLAGS += -O3 -march=native -fno-math-errno -fno-trapping-math(plus an empty line at the end...
If you have suggestions on how to improve the language, eitherfile an issueor discuss C3 on its dedicated Discord:https://discord.gg/qN76R87. The compiler is currently verified to compile on Linux, Windows and MacOS. Support matrix
